LUBRICATOR.

Specification of Letters Patent.

Patented June 7, 1910.

Application filed April 22, 1909. Serial N0. 491,588.

To all whom it may concern.'

Be it known that I, PETER J. SWEENEY, a citizen of the United States ofAmerica, residing at Windsor, in the Province of Ontario and Dominion ofCanada, have invented certain new and useful Improvements inLubricators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention relates particularly to a novel type of lubricator,especially designed for lubricating the pistons of explosion engines,and consists in the construction of the lubricator, in the arrangementand combination of its parts, and in certain details of construction aswill be more fully hereinafter set forth.

In the drawings, Figure 1 is a view in elevation of a lubricatorembodying my invention; Fig. 2 is a similar view, partly in section; andFigs. 3 and 4L are enlarged perspective views of some of the lubricatorparts detached.

The primary object of the invention is to provide a lubricator that maybe applied to the explosion chamber of an engine or m0- tor, and inwhich the oil feed will not be interrupted by the explosion. With thisobject in view, I have constructed the lubricator with a check-valve forcontrolling its discharge passage, and with a baffle serving to deflectsuch of the explosion gases as are not checked by the valve away fromthe feeding device. I have also preferably constructed the lubricator insuch manner that the baille in deflecting the gases will assist thevalve to close, thereby reducing to a minimum the amount 0f lexplosiongases that may enter the discharge passage.

Referring to the drawings, the referenceletter A designates thereservoir or oil cup of the lubricator, B the usual sight feed chamber,C the feed tube, and D the discharge passage formed in the externallythreaded nipple E, preferably made integral with the wall of the chamberdescribed.

F represents the check-valve controlling the discharge passage, Gr is abailie member arranged within the chamber over the inlet end of thepassage, and I-I is preferably a rigid connection between the parts.

I designates the cylinder, formed preferably with an internally threadedapertured boss J adapted to receive the nipple E of the lubricator, andK is the piston to be lubricated.

Assuming that the lubricator is applied to the explosion chamber of thecylinder and the parts to be in position as indicated in Fig. 2, whenthe explosion takes place the valve F will be raised and will engage itsseat a, and such amount of explosion gases as may enter the dischargepassage before the valve closes will strike against the baffle, therebyassisting the closing of the valve, and will be deflected to the wallsof the sight chamber away from the tube C so as not to interfere withthe feed. Upon the return- 1 stroke of the piston the valve will leaveits seat automatically through the action of gravity, allowing thelubricant to pass within the cylinder in the desired manner.

To render the baiiie member more effective, I preferably form the samein the shape of an inverted cup, as shown, the depending wall of whichprevents escape laterally of the explosion gases, compelling them topass downwardly and to strike against the bottom of the chamber. Thisform of baffle is also more effective, for obvious reasons, in assistingthe operation of the valve, causing the same to close more rapidly thanwhere the action of the eXplosion gases is upon the valve only.

Any suitable construct-ion of valve and bafliev may be employed, but Ihave here shown the preferable construction, the valve being formed bythe head of a screw-bolt L, the shank of which has a threaded engagementwith the baflie and to retain the parts in their xed relation to oneanother I preferably turn over the upper end of the screw, as at b,after the parts are assembled.

While the lubricator described is especially designed for application tothe explosion chamber of the cylinder, it may be applied to other partsthereof wherein ,the feed will not be affected by the explosion exceptby slight leakage. In such instances the valve would be normally awayfrom its seat and the baffle would Acontact with the chamber wall. 'Iopermit the lubricator to feed properly under such conditions, I form anumber of lateral ports, as c, in the lower portion of the bafiie,preferably its lower edge, which allows the oil from the tube to enterwithin the discharge passage andfeed constantly therethrough.

What I claim as my invention is,-`

l. In a lubricator, the combination with a reservoir provided with asight feed chamber and a discharge passage leading therefrom, of a checkvalve controlling the passage, a movable baffle member within thechamber comprising an inverted and later ally ported cup-shaped memberarranged over the pasage inlet, and a rigid connection between thebaille member and valve.

2. In a lubricator, the combination with a reservoir provided with asight feed chamber and a discharge passage leading there- Jfrom, of acheck valve at the lower end of the passage, an inverted and laterallyported cup-shaped baille arranged within the chamber over the upper endof the passage, and a rigid connection between said batlie and valveextending through the passage.

3. In a lubricator, the combination with a reservoir provided with asight-feed chamber terminating in a threaded nipple, said ber and adischarge passage leading therethrough and the end of said nipple beingrecessed to form a valve seat, an inverted cup-shaped baille arrangedwithin the chamber over the upper end of the passage, having a pluralityof open-ended recesses formed in its edges, a check-valve engaging thevalve seat in said nipple, and a member formed integral with the valveextending through the passage in the nipple and forming a rigidconnection between the valve and batlie.

,4. In a lubrlcator, the combination with a reservoir provided with asight feed chamber, of a member forming a portion of the chamber havingan opening or aperture forming a discharge passage, a check` valvecontrolling the passage, a movable baiiie member arranged within thechamber over the passage inlet and adapted to seat upon said aperturedmember, and a connection between said valve and baiile whereby thelatter assists in the closing of the valve, there being a communicationbetween said chamber and the discharge passage in the seated position ofthe baffle.

5. In a lubricator, the combination with a reservoir provided with asight feed chamber, of a member forming a portion of the chamber havingan opening or aperture forming a discharge passage, a check valvecontrolling the passage, a movable baille member arranged within thechamber over the passage, a connection between said valve and battlewhereby the latter assists in the closing of the valve, the baillemember being adapted to seat upon the apertured member, and one of saidmembers being provided with a recess forming a means of communicationbetween said chamberv and the discharge passage in the seated positionof the baffle.

In testimony whereof I aliX my signature in presence of two witnesses.
